Specification forming part of Letters Patent N0. 40,483, dated November 3, 1863 ,"antedated October' 24, 1863.

To all whom, it may concern:

Be it known that I, SETH C. HOWES, of South Chatham, in the county of Barnstable and State of' Massachusetts, have invented a new and useful Improvement in Planes for Beading, Molding, &c., Snc. and I do hereby declare that the followin g is a full, clear, and exact description of the saine, reference being had to the accompanying drawings, making a part of this specification, in which- Figure lis a vertical section of my invention, taken in the line 00 a', Fig. 2; Fig. 2, a plan or top view otA the same; Fig. 3, a side vi ew of' the same Fig. 4, a detached face View of' the clamp which holds the planeiron in proper position.

Similar letters of reference indicate correspondin g parts in the several figures.

vThis invention relates to an improvement in that class of planes used by joiners for forming beads and moldings, and also for forming rabbets, and which discharge the shavings at the side of the stock.

The object of' the invention is to obtain a plane of' the kind specified which will discharge the shavings freely and without the liability of choking or cloggingin the throat, and one also which will admit of the iron being adjusted with the greatest facility to regulate the depth of cut and admit of' the iron being firmly secured in the stock.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents the stock of the plane, which is constructed of wood, and of the usual form, and B is the iron,77 the lower end or cuttingedge of which is made of a form corresponding to that of' the bead, molding, or rabbet to be cut. This iron has a notch, a, made in its back surface, near its upper end, and into this notch a projection or spur, b, on. a nut, C, is fitted, said nut being in an inclined recess or groove, a, in the stock. The nut C is on a screw, D, the upper part of which is iitted in a metal socket, E, placed in a recess in the upper part of` the stock. AThe upper part of the plane-iron is fitted in the front part of the recess or groove c, while lthe lower part passes through a recess, F, which is open at its side, and forms what is commonly termed the throat, to admit of' the shavings cut by the iron to pass out from the stock. This throat is narrow at its lower end, as shown at d, and it widens very gradually for a short distance upward, and then suddenly expands or increases in width, with a rounded front, e, as shown clearly in Figs 1 and 3.

Within this enlarged part of' the throat there is fitted a metal socket or guide, G, in which a clamp, H, works. This clamp is also constructed of' metal, and maybe described as being formed of arectangular bar, having one side beveled, as shown. at f. (See Fig. 4.) The clamp is allowed to work freely in the socket or guide G, and it is moved or operated by a screw, I, which works in an internal screw-thread, g, in the clamp, as shown in Fig. 1, and is fitted in a metal socket, J, placed in a recess in the upper part of' the stock. The portions of the screws I and D, which are fitted in the sockets E and J, are smooth, (see Fig. 1,) and the beveled surface f is placed outward.

From the above description it will be seen that by turning the screw-rod D, the iron may be raised and lowered according to the depth of' cut or thickness of' shaving required, as by turning said screw the nut C is moved, and with it the iron, and when the desired set o1" the iron is obtained, the latter is securedl in position by pressing the clamp H against it, the latter result being attained by turning the screw I. The back part of the iron is pressed by the clamp Hl firmly against the back part of' the throat F.

In using the implement the shavings will readily pass up the lower narrow part of the throat, and in passing into the enlarged part they will turn f'reely the rounded corner c, and, coming in contact with the hard, smooth metal surfaces of the inner side of'the socket or guide G, and the beveled surface f, of' the clamp H, are discharged freely from the throat, and all choking' and clogging of' the latter avoided.

The ordinary throats of this class of' planes are very liable to choke or clog with shavings, as they have a comparatively long narrow opening at their lower parts, and are not provided with any metal surfaces, which screw J, and curved throat e, allY constructed have a tendency to prevent the sticking or and operating together, as herein shown and adhering of the shavings in the throat. described.

Having thus described my invention, I SETH C. HOWES. claim, as an improved article of manufacture- Witnesses: Y
